Abstract

The Web Real-Time Communication [WebRTC] working group is charged to
provide protocol support for direct interactive rich communication
using audio, video and data between two peers' web browsers. With in
the WebRTC framework, Session Description protocol (SDP) [RFC4566] is
used for negotiating session capabilities between the peers. Such a
negotiation happens based on the SDP Offer/Answer exchange mechanism
described in [RFC3264].
This document provides an informational reference in describing the
role of SDP and the Offer/Answer exchange mechanism for the most
common WebRTC use-cases.
This SDP examples provided in this document is still a work in
progress, but it aims to align closest to the evolving standards
work.
